| 摘 要： | 将两种熔融流动指数（ＭＦＩ）相差大的聚丙烯（ＰＰ）分别与一低密度聚乙烯（ＬＤＰＥ）进行共混，用熔体流动速率仪测定其流动特性。发现ＭＦＩ值高的ＰＰ，当共混比ＰＰ／ＬＤＰＥ为５０／５０时，其熔体流动速率（ＭＦＲ）为最大，本文对此作了初步的分析和讨论。

| Abstract: | In this paper , two polypropylenes (PP) with very different in melt flow index (MFI) were blended with a low density polyethylene (LDPE) respectively, and the flow properties of the samples were studied by using a melt flow rate apparatus. It was found that, for the higher MFI PP. the melt flow rate was maximal when the blending ratio of PP/LDPE was 50/50. This phenomenon was analyzed and discussed. |
